T all 10710712 it may concern:

Be it known that 1, Tire) AS hlANDEYILLE liiOPPE'R, citizen of the United States, residing .t lilu'll'ern, in the county of llockland,

State of New York, have invented certain new and useful improvements in Railway- Frogs, of which the following is a specification, reference being had to the accompanydrawings, forming a part hereof.

My invention relates particularly to means for securely holding the parts of a railway l frog in their proper positions with relation to each other, and the invention consists in the new and novel features of construction in means for wedging and securely holding the parts together in proper position.

By this constriu-tion the number of parts in a frog block is greatly reduced. instead of bolts the parts are held together by projecl'ions which are integral with the block 05 i self and which permit keys or cotters to be used. instead of nuts or nut locks. Greater safety results and the liability of the parts of the frog working apart is reduced to a minimum. The parts of the frog are readily and quickly assembled and in case of wear or injury the damaged part can be easily removed and. replaced.

15 combinations of parts hereinafter set forth Although l. have shown my invention cmand claimed. bodied in one particular kind of frog it is ob- Figure 1 is a plan view of a railway frog vious that the invention may be employed embodying my invention. Fig. l is a side elevation showing one form of holding 20 means. Fig. 3 is a cross section on the line 33 of Fig. 1.

The frog comprises the main rails A, the wing rails B and the frog block C in the usual manner. These parts may be of any pro- 25 ferred material and of any desired section, although my invention will be found of special value in connection with frog blocks of a tough or hard material such as manganese steel.

00 In order to securely hold the parts of the frog together and in their proper relative poin connection with any of the well known types of frogs now in use. I t is obvious also that various changes may be made in the details of the construction herein shown and described which changes are *ithint the limits of nuichanieal skill and which may be made without departing from the invention provided the means set forth in the following claims be employed. 7 5

I claim as my invention: 1.. in a railway frog the combination with a track rail provided with an opening therethrough, of a frog block provided with a projection formed integral therewith and arsitions the frog block C provided with one ranged substantially at right angles to the or more arms or projections (Z formed intecenter line of the block and projecting gral therewith. Preferably these arms or through said opening, and means removably 35 projections are circular in section, although l secured at or near the end of said projection they may be of any desired section, and are to engage with the parts of the frog adjacent preferably formed in pairs on opposite sides l to said frog block. of the frog block substantially at right angles 2. in a railway frog, a frog block provided to the center line thereof, such pairs being l with a projection formed integral therewith 40 provided at suitable distances apart throughl and having a perforation near its end, and a out the length of the block. The webs of l wedge key removably secured in said perfothe adjacent wing and main rails together j ration and adapted to engage with the parts l l l with the strap or reinforcing bar 0, if any be of the frog adjacent to said frog block. used, are formed with corresponding open- 3. In a railway frog. the combination with ings or passages f through which the arms or a track rail provided with plurality of projections (Z extend. At or near their outer 1 openings in its web, of a frog block provided ends the arms or projections are provided with a plurality of projections formed in pairs opposite each other and extending through said openings, and means rcmovably with perforations (Z to receive wedge keys, beveled cotter pins or any other suitable secured at or near the end of each of said projections to engage with the parts of the frog adjacent to said frog block. l 4. In a railway frog, the combination with J the main and Wing rails having openings formed in the Webs thereof, 01"" a frog block l provided with a plurality of projections passmg through the openings provided 111 said rails, and Wedge keys engaging saidpro eo- I tions to Wedge the parts together and hold 10 the same against displacement, substantially as described.
